WASHINGTON — In unlikely alliance, the Obama White House and House Republicans joined forces Thursday in a furious attempt to pass a $1.1 trillion government wide spending bill over clamorous protests from Democrats who said it would roll back bank regulations imposed in the wake of the economic near-meltdown of 2008.House Democratic Leader Nancy Pelosi delivered a rare public rebuke to President Barack Obama, saying she was “enormously disappointed” he had decided to embrace legislation that she described as an attempt at blackmail by Republicans._______________The White House noted its own objections to the bank-related proposal in a written statement. Even so, officials said Obama and Vice President Joe Biden were both calling Democrats in an attempt to secure enough votes for passage of the broader measure, which combined government spending and a new course for selected, highly shaky pension plans.The outbreak of Democratic bickering left Republicans in the unusual position of bystanders rather than participants with the federal government due to run out of funds at midnight. Despite a lengthy, unplanned break in the House’s session, there appeared to be no threat of a shutdown in federal services.
